Changzhou Giant Bearing Co., Ltd

Most bearing grades of stainless steel (440C) do not fare well in sea water after a period of time. Richer CHROME content stainless steels are usually too soft for bearing applications. One surprisingly economic solution is THIN DENSE CHROME (TDC). TDC provides an extremely hard and corrosion resistant solution for sea water applications. Combined with Stainless balls and plastic cages. The TDC coating covers 100% of both inner and outer rings with tight control on plating thickness of the raceways. Please ask AHR for what we can do in this area.
